the other day on my way home from work i had to stop twice because my car was pegging out the temp gauge. i figured i would replace the t-stat first because its the cheapest for one and it was kind of a sudden thing. the car usally ran a little past the half way mark. i replaced the t-stat and found that the one that was in it was in two pieces,sure fix. nope still runs hot but not pegging the gauge out. looked at the radiator and it looks like it might be the side tanks leaking any one had this problem? i really dont want to put in a new radiator,not that i couldnt but i dont want to spend the money. any sugg.?
